Fractal globule
From Wiki @ Karl Jones dot com
A fractal globule (or crumpled globule) describes polymers that have compact local and global scaling.
Description
They can be modeled through a Hamiltonian Walk, a lattice walk in which every point is only visited once and no paths intersect, this prevents knot formation.
A crumpled globule forms through local regions crumpling, i.e. collapsing in on themselves and this iteratively occurring over the whole polymer.
This process follows the space-filling Peano Curve.
It has been proposed that mammalian chromosomes form fractal globules.
